YORK, N. Y., A CORPORATION on NEW MATERIAL-\VO RKING MECHANISM.

Application filed iAugust 22, 1924. Serial No. 733,494.

I This invention relates to material working mechanisms, and more particularly to a combined slittingand rewinding machine for the purpose of slitting a comparatively wide web of material into strips.

An object of the invention is to provide an improved Compact material workingmechanism of the above mentioned type which is so organized and arranged as to attended by the operator. 7

Another object of the invention is to provide an improved means for supporting, aligning, and driving cooperating work .performing members.

In accordance with one feature of the invention there is provided with a mechanism for slitting a metallic web into a plurality of strips, 9. rewinding mechanism designedto take up each strip at right angles to the direction of delivery from the slitting mechanism and upon a reel independently driven.-

the rewinding mecha- Also arranged below for automatically tak nism is a mechanism up and compacting the scrap material as it accumulates.

In accordance with another feature of the invention there is provided two series of slitting members suitably spaced upon sleeves rotatably secured to driving shafts over hanging the supporting frame of the slitting mechanism, the sleeves being adapted to in terlocl: in mounting them upon that the cooperating slitting .members carried thereon will be correctly aligned and the securing of one sleeve from longitudinal movement upon its shaft retains the other sleeve. The overhanging shafts permit the slitting men'ibcrs to be readily and easily removed therefrom. The shafts are gear driv manner which permits a comparatively Wide range'of adjustment between the slitting members as they wear without being limited by the pitch diameter of the driving gears. i

It is believed that the invention will'be clearly understoodfrom the following de scription and the accompanying drawings, in which a Fig. 1 is a side elevation of a mechanism be efficiently the shafts so web.

Fig. 12 'isa vertical sectional view taken upon the line 12 12 thereof, looking in the direction indicated by the arrows.

As shown in Fig. 1 the mechanism comprises a main frame or table 14 which serves as a stand for supporting a supply reel 15 and a rewinding mechanism 16 comprising a plurality-0f take-up reels 17 for the slit The slitting mechanism'is indicated at 18 and the automatic scrap take-up mechanism at 1-9. The mechanism illustrated is designed to slit a Web into nine strips of equal width and rewind them upon separate reels, each of the reels being independently driven, but it will readily be understood that the number andwidth ofthestripsfto be- 1 slit ing mechanism.

7 The slitting mechanism comprises a pair ofshafts 20 and 21: suitably 'j'ournaled in vertical arrangement upon standards 22 and 23 arranged upon the left-hand end of the frame 14 as v1e'wed in Fig. 1. Also journaled upon the standards 22 and 23 directly below the shafts and 21 is a main drive shaft 24 driven through gearing indicated in dotted outline at 25 in Fig. 2,-wh1ch is driven from a motor indicated at 26. The shaft 24 through a sprocket wheel 27 and a pulley 28 aflixed thereto drives the take-up reels 17 and the scrap take-up mechanism 19 respectively through cooperating means which will be re necting the standards 22 and '23. Also rotatably mounted uponthe bracket 33 and 1n vertical and horizontal alignment with the shafts 32 and 20 respectively is a shaft 37.

Aflixed to the. shaft 37, and offset with respect I to the gear 30, as viewed in Fig. 6, and adapted to mesh with the wide faced gear 31 is a gear 38 in turn meshing with a gear 39 secured to the shaft 20.

Thes-tandards 22 and 23 areeach provided with an elongated opening 40 within which areslidably mounted journals 43 for supporting the shafts 20 and 21. Suitably mounted between each pairof vertically disposed journals 43 is a compression spring 44, and

screw threaded into the top surface of each .of'thelstandards 22 and 23 is an adjusting screw 45, the lower ends of which engage the top surface of the ournals43 associated with the shaft 20. By turning the screws 45 down it will readily be seen that the shaft 20 will,

be moved downward against the compression of "the sprlngs 44, and upon turning the screws 45 upward the springs 44 function tomove the shaft 20 upward. The purpose of this vertical adjustment of theshaft with respect to the shaft 21 will be madeapparent later on in, the description. It will thus be evident that upon 'a'rotary motion being applied to the shaft 24 in the direction indicated by the arrow in Fig. 7, that the shaft 21 will be rotated in a clockwise direction through the cooperating gears 29 and 30, the latter gear causing the rotation of the wide faced gear 31, which in turn drives the gear 38 mounted directly thereabove and thereby,

causes the'rotation of the shaft 20 in a coun- -ter-cloekwise direction through the co -operating gearq39. v Th'eshafts 20" and 21 extend outside of the right hand side of thestandard 23 and mounted upon each of the shafts is a set of slitting disks46 and 47 respectively.

The overhanging ends ofthe shafts 20 and 21 are each provided with an integral collar 48 which lies snugagainst the surface of the ournals 43. Secured to the shaft 20 by keys 50, indicated in dotted outline, is a sleeve 51 mountin a plurality of slitting disks 52' and by a spacing ring 53. The slitting disks 52',

spacing rings 53, and aligning collars 55 are clamped; upon the sleeve 51 and against the head 54 formed thereon by a clamping nut 58 screw threaded upon the sleeve 51. .A second clamping nut 59 screw threaded upon the end of the shaft 20. prevents any longitudinaldisplacement of theassembled sleeve upon the shaft 2O by clamping it against the collar 48. A sleeve 61 similar to the sleeve 51 uponthe shaft 20, is similarly keyed] to the shaft 21 and also carries a plurality of disks 62' and spacing rings 63. 'An' aligning collar suitably spaced, upon the sleeve 61 by the spacing rings" 63 ;cooperates with the spaced ali ning collars 55 upon the sleeve 51 to accurately align-the disks 62 which have been suitably spaced .upon the sleeve 61 by the spacing rings 63 to align with the space between the disks 52 mounted upon the sleeve 51. The

disks 62, spacing rings 63, andthe' aligning collar 65 are clamped upon the sleeve 61 and against ahead 64 formed thereon bya clamping nut 68. The disks 5 2 and 62 being assembled correctly upon the sleeves 51' and 61 respectively, and thereafterthe sleeves upon the overhanging ends of the shafts 20' and 21 respectively, provides a' mean for readily re-s moving or mounting the assembled slitting unlts upontheir respective supports. No accurate ad ustment of one'set of slitting disks with respect to the other is necessary when mounting themfin position upon the shafts 20 and 21, it being merely necessary to align the collar 65 between the'collars 55 and slidethe sleeves 51 and 61 in position upon the shafts 20 and 21 respectively, thereafter the two slitting units are retained longitudt nally upon theshafts 20 and 21 by threading the clamping nut 59 upon'the end of the shaft20. I

Due to the mounting ant; driving arrange ment of the slitting disks :1. heretofore described, a large range of'adj made as they wear without being limited by the pitch diameter of the driving gears. As wear shows on the disks, the screw 45 may be turned down against the action of the spring 44 until the proper slitting relation exists between the slitting edges of the disks 52 and 62.

A supply reel 15, which-will he described in greater detail hereafter is carried upon a bracket 69 supported upon the frame or table 14,.and the web/70 to he slit isrled' therefrom and undera roller 71. riding in a bath of'some suitable lubricant, which may be water, indicated at 72, the purporeof which is'to. wet the ustment maybe I ing arbors 114 supporting the upper row of reels 17. t will thus be seen that upon ro tary motion being applied to the main drive shaft 24 that each of the take-up reels 17 will be independently driven through the associated'sprocket wheel 27, chain 104, sprocket wheel 103, bevel gears 197 and 108, shafts 109 and 117 operatively connected together by the sprocket wheels 119 and 129, and chain 118, the rotary motion of the shafts 109 and 117 being transmitted to the reels 17 in the lower row through the pulleys 110, 111, belts 115, and to the reels 17 in the upper row by the pulleys 123, 125, and belts 124. By driving each take-up reel 17 through a belt independently of the others, a uniform tension is maintained upon the strips 78, which is c esirable in the rewinding of certain materials.

Adj ustably supported tor vertical move ment upon the front face of each of the brackets 101 a pulley 123 for guiding the strips 78 after leaving the cleaning device 95 on theirway to the reels 17. As will be observed from Figs. 1 and 2, each of the pulleys 126 is positioned in a different vertical and horizontal plane so as to maintain the strips separate and prevent interference or tangling between them. Between the pulleys 126 and the take-up reels 17' the strips receive a 90 twist, which produces no deleterious effects thereon, due to the comparatively long distance between the pulle s 126 and the reels 17.

. Reinovably mounted upon the opposite side of thehead 132 is a second thin circular plate 134 the two plates bein separated b a circular flange-like portion 137 formed on the head 132. Rotatably secured to the portion 137 by a key. not shown) is a strip or strand carrier 133 of the type'illustrated and d scribed in the patent to F. S. liochendor.

No. 1,545,906, issued July 14, 1925, towhich reference may be had for a more detailed illustration and description.

Secured to the outside flat face of the plate 134 is a pair of spring pressed diametrically opposed latches 139, the latching ends 140 of which are adapted to readily engage in. a continuous circular channel- 141-1 formed in a shouldered portion of the head 132. The latches 139 are each securec to theplate for radial movement by a pair of soouldered rivets 144-secnred to theplate 134, which ride in slots .145. formed in the latches 139. The outside end of each of the latches 139 is bent outward at right angles to the main portion, as indicated at 146, to form a handle for ma nipulating the latch against the action of a spring 147 positioned under tension between a housing 148 atlixed to the plate 134 and a face ofthe handle 146 as clearly indicated in Fig. 9. To remove the loaded strip carrier 138 from the reel 17, the operator inserts his iands between two of the reels 17 and pulls outward upon the handles 146 of thelatches 39 against the action of the springs 147, which. movement brings the latching ends 140 of the latches 139 out of the channel 141, and then by movingthe plate 134 parallel to the axis of the winding arbor 114 it may be moved so that the loaded carrier 138 may be easilv.

Associated with the head 152 is a second head 154 in the form' of a thin circular plate having a plurality of tapered pins 155 concentrically arranged, which form a hub upon which'th'e web is wound. a shouldered knob or handle 158. A reduced circular portion 159 of the handle 158 is cut away as indicated at160 within which is mounted a spring pressed latch 161, which is pivotally mounted upon a pin 6 In'its Secured to the head 154 is latched position an engaging end163 of the latch 161 enters a circular channel 164 formed in the splndle 153 under the action of a compression spring 166.- To remove the head 154 from the spindle the latch 161 is turned counter-cloclnvise about the pin 162- by pressing inward upon a knurled knob 167 formed upon thelatch 161 and against the action of the spring 166, thereby raising the engaging end 163 of the latch from the circular channel 164 and thereafter the head may be slid from off the spindle 153. i

1n the manufacture of the web 70 it may be taken up directly during its fabrication upon a reel similar to the reel 17 ust decribed, and at times when the web 7 O is being irodnecd at a greater speed than it is being 5 slitinto the strips 78 by the slitting mechanism 18, the coil or web 70 may be readily and easily removed from the head 154 and stored until ready'to use by simply turning the tapered pins 155 downward and gently tapping the head 154, whereupon the coil of web will drop off of the tapered pins. Thecoil of web may be readily mounted upon the head 15a again by pressing it into position around the tapered pins 155, as originally coiled.

The operation of this mechanism is as foldisks 46 and 4'? where it is slit into the strips 78. The scrap material 79 removed from the edges or" the web is led under the fingersSO and wrapped around one of the pins 93, forming the hub of the reel 83. From the slitting disks the strips 78 are threaded between the emery wheels 96 and thereafter they are each passed around their respective guiding pulley 126, given a twist of 90, led upward and suitably secured to their respective carrier 138. Uponstarting the machine the web 7 0 V is continuously drawn from the supply reel I 15, slit into a plurality of strips 78, each strip being wound upon a separate reel independently driven to provide a uniform tension upon the strips, which in the case of material of a fragile nature is very essential.

r As the strips are being wound upon their respective reels or carriers, the scrap removed from the sid s of the web during the slitting operation is automatically taken up on the reel 83, the apron 87 under the action of the spring 92 automatically compacting the scrap upon the reel. The wide surfaces of 1 the strips are brushed and cleaned by the emery wieels 96 before being wound upon the reels 17 to remove any burrs that might be formed thereon during the slitting operation, or of any foreign matter thereon which may be necessary on account of the use to which the strips may be put. Also at timesdue to flaws developed in the web 70 during its fabrication, abrealr may occur in one or the other of the strips, whereupon the machine is stopped, the break repaired by lapping the ends, sometimes leaving this particular strip a trifle short, but due to the separate drive for each reel or carrier, the tension upon the repaired strip as it continues to be taken up is not increased as it naturally would be if all of the strips were taken up on a single spindle.
